New neurons are incorporated into the high vocal center (HVC), a nucleus of the adult canary (Serinus canaria) brain that plays a critical role in the acquisition and production of learned song. Recruitment of new neurons in the HVC is seasonally regulated and depends upon testosterone levels. We show here that brain-derived neurotrophic factor (BDNF) is present in the HVC of adult males but is...

Long-lived species are particularly susceptible to bioaccumulation of lead in bone tissues. In this paper we gain insights into the sublethal effects of lead contamination on Egyptian vultures (Neophron percnopterus). Our approach was done on the comparison of two populations (Canary Islands and Iberian Peninsula) differing in exposures to the ingestion of lead ammunition. Blood lead levels wer...

Echovirus 13 (EV13), considered rare, was reported worldwide in 2000, mostly related to aseptic meningitis outbreaks. In Spain, 135 EV13 isolates were identified. The genetic relationships between 64 representative strains from Spain and other reported isolates from the United States, Germany, Italy, Japan, and Sweden were described by analyzing the partial sequence of the major capsid protein ...

Classical, mitochondrial DNA (mtDNA) and Y chromosome markers have been used to examine the genetic admixture in present day inhabitants of the Canary Islands. In this study, we report the analysis of ten autosomal Alu insertion polymorphisms in 364 samples from the seven main islands of the Archipelago, and their comparison to continental samples. The detection of population-specific alleles f...

3D integration is a promising advanced manufacturing process offering a variety of new hardware security protection opportunities. This paper presents a way of securing 3D ICs using Hamiltonian paths as hardware integrity verification sensors. As 3D integration consists in the stacking of many metal layers, one can consider surrounding a security-sensitive circuit part by a wire cage. After exp...

Distributed Hash Tables (DHTs) may suffer from a high lookup latency due to the issue of topology mismatching between the overlay and the physical underlying network. To handle this problem, recently, some researchers use network coordinates (NCs) to construct topology-aware DHTs(e.g. Canary). However, these proposed DHTs still have room to be improved due to the inaccuracy of NCs. To construct...

In this work it has been developed a novel system of automatic recognition for trees leaves, based on a hybrid classification method by means of a Support Vector Machine (SVM), using the Fisher kernel, and calculated from a Hidden Markov Model (HMM). An angle sequence has been used as an element of parameterization, extracted from the leaves contour, making such sequence invariable by rotation,...

Over the last decade, numerous papers focusing on the fauna of the Canary Islands have reported that many spectacular species radiations have taken place, leading to a very high level of endemicity in this archipelago. The species of the genus Pholcus are a very good example of such a fascinating process. The Canary Islands harbor the highest number of endemic species of this genus. Therefore, ...
